This invention relates to new and useful improvements in hospital or invalid beds,

and has for an object thep rovision of a bed including means whereby the bed sheets may be readily and quickly changed without mov ing or otherwise disturbmg the occupant of More specifically the invention provides an invalid or hospital bed including means positioned beneath the bed in combination with apair of mattresses, the parts being so arranged that one mattress with its sheet may be rolled from under the patient as the second mattress and its sheet are moved into position under the patient.

Other objects and advantages will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawing wherein one satisfactory embodiment of the invention is shown. However it is to be understood that the description and drawing are for the pur pose of making clear the construction and operatlon of the principles of the invention and are not to be considered a limiting of its scope since changes in construction, combination and arrangement of parts may well be made within the scope of the appended claims to which reference must be had for a w? definition of the limitations of the invention.

of the links v with attached hooks.

Referring in detail to the drawings, the bed includes a head and a foot 5 and 6 respectively, each comprising legs or uprights 7 and 8 connected by cross pieces 9 and 10. Extend- J ing between the head 5 and foot 6, at each side of the bed are the side rails 11, preferably somewhat L shaped as shown in Fig. 2.

.Disposed' beneath the bed, at the head and foot thereof, are pairs of standards 12 and 13 at their upper ends providing bearings for I or the like is disposed on the mattresses and rollers 14 and15." These rollers are disposed on shafts 1(3 and 17 respectively, and on the shafts at the ends of-the rollers are discs or plates 18, the discs and rollers forming spools. Straps. or other means 19 are used for securing the standards l2-and 13 to the legs or uprights 7 and 3, and if necessary they may also be further fastened by securing them to the floor.

Mattresses 20 and 21 are used with the so bed, and sheets 22 and 23 are associatedwith the mattresses. As clearly shownthe sheet 22 is buttoned to mattress 20 at 24 and a por tion'of the mattress and its associated sheet is wound about the roller 14. The end of the mattress 20, remote from thebuttons 24, is secured to a ropeor cable 25 as at 26 and the cable is secured to the roller. A crank 27 is .shiftable from shaft 16 to shaft 17 in order that either roller 14 or 15 may be wound. V

The mattress 21 and sheet 23 areshown as occupyingthe most of the bed. Sheet 23is buttoned to mattress 21 as at 28 and 29. Also one end of mattress 21 is connected to a rope or cable '30 as at 31,-and the other end of cable 30 is secured to roller 15-. As is clearfrom the drawing, mattresses 20 and 21 are doubled on themselves about rollers 32 and 33.: Theends of the rollers rest in the L shaped side rails 11 and have extensions 34 connected at each' side of the mattresses by links 35;

- The links 35 hold the rollers 32 and 33 in definite spaced relation, there being space'between-the rollers to "accommodate the two mattresses and sheets with but little space to-spare. Also, see Fig.2, it is to be noted that the links and'rollers receive the side rails 11 between them. A roller 36 of soft rubber occupies the space between them.

In the operation of the device, assuming; that the mattress 21 and sheet 23 are in place and it is desired to change, the crank 27 is applied to shaft 17 and the shaft rotated to wind the mattress on to roller-15 after sheet 23 is unbuttoned at 29. Preparatory to wind-, ing the mattress 21 onto roller 15 sheet 23 will be unbuttoned as at 29 whereupon said sheet will fall to the floor and by unbuttoning it at 28 it can be removed.

During the time the foregoing operation is taking place, owing to the links connecting rollers 32 and 33, mattress 20 and sheet 22 are moved or rolled into place. Roller 36 prevents-the patient from being-caughtand pinched between the mattresses.

In this connection it will first be necessary to secure the links 35 to one end of the bedstead so that the rolls 32 and33 -will be held in position during and after the removal of the mattress. I have therefore mounted a pair 01' oppositely extended hooks 3: upon each of the links 35, each hook adapted to engage a pin 38 upon abed post, two ot'said.

hooks, one of each pair, serving to secure the llnk and the rolls carried thereby to the torward bed posts and the remaining two hooks to secure it to the other two posts;

spect, it will also be understood t in question are carried upon the bedstead and held through hnks and hooks to the posts at while the other end portion of the mat eat the rolls the end.

Now when it is again desired 'to change the 'Sl168l one end of a clean sheet is'securedby buttons 28, and sheet-22 is unbuttoned from mattress 20 and the mattress wound onto roller 14. The clean sheet is moved into place beneath the occupant ofthe bed on mattress .21 as the latter is moved or rolled into place beneath the patient.

Having thus described the invention, what I claim is:

1. In combination, a bed, it'pdll of-mat- ,tresses, means beneath the bed onto which themattresses maybe wound and means whereby as one of the mattresses is moved fromthe bed the other is moved into place on the bed.

2. In combination, a bed, a pair of neat means for securing a sheet to each of said mattresses, a pair of rollers, said mattresses doubled upon themselves about said e s, means connecting said rollers whereby they move together, means beneath the bed onto which the mattresses ma be wound. J

and means for operating said last means", said rollers cooperating whereby as one oi said mattresses is wound onto said means the rollers are moved and draw the other mattress into place on the bed.

3. The combination as in claim 2, said bed having side rails and the roller-sand connecting means engaging said side rails and being guided thereby.

4. The combination as in claim 2, including a roller disposed. on top of the mattresses in a position between the rollers about which the mattresses are doubled.

5. In a bed, the combination of a bedstead, a pair of mattresses, one end of one of which is detachably connected to one end of the bedstead and an end of the other mattress being'iattachedto the other end of the bedstead, rolls carried by the bedstead over which said mattresses are carried, separate means beneath the bedstead upon. which each of the mattresses are wound, and means for retaining the rolls adjacent either end of the bedstead while the mattresses are attached or removed.

6. In a bed, the combination of abedstead,

a pair of rolls mounted to travel thereon,

links connecting the ends of the rolls, a mattress carried by each roll one end of eachof said mattresses being detachably connected to one end of the bedsteach means for. drawing the mattresses over the rolls to shittthe position the rmrttresseaand pivoted means on the links for connecting the links to the bedstead to permit the attachment-or removal of a mattress.
